Both Star Trek and Battlestar Galactica feature young women named Miri.  On Star Trek ("Miri" - written by Adrian Spies; directed by Vincent McEveety), Miri is played by Kim Darby.

On Battlestar Galactica ("The Young Lords" - written by Donald Bellisario, Frank Lupo and Paul Playton; directed by Donald Bellisario) Miri is played by Audrey Landers.
